Authorities have recovered two vehicles from a lake in western Oklahoma containing the remains of six bodies that may be those of people missing for decades, the Associated Press reports.

According to reports in The Daily Elk Citian, one of the vehicles appears to match a Camaro that went missing in 1970 along with three teenagers from the small town of Sayre. The other car, an older-model Chevrolet, may be the same vehicle that disappeared along with Canute residents in the late 1950s or early 1960s. Reports originally stated that three bodies had been recovered from the Camaro and two from the Chevrolet; a local sheriff announced Wednesday that three bodies were also found in the Chevrolet.

The remains have not yet been identified but a spokesperson for the Oklahoma Highway Patrol said she hopes the discovery will offer relief to families left wondering for decades what became of loved ones who simply vanished.

“We’re hoping these individuals, that this is going to bring some sort of closure to some families out there who have been waiting to hear about missing people,” she told the AP. “If that’s the case, then we’re thrilled we were able to bring some sort of closure to those families.”
